I'm unable to replicate this. While Sublime Text doesn't log anything for this scenario, my hunch about the underlying problem would be a misbehaving Quick Look plugin, and there may be some information logged about that by OS X to Console.app, which you can find under Applications/Utilities.

Another way to narrow down the problem is to find a folder that causes the issue, move all the files out of it and see if the problem goes away, and then start moving the files in one by one until you find the one that triggers the issue.
